Covington’s center stands about 1,630 ft above sea level. Within three miles the land runs from 1,290 ft to 1,750 ft, a difference of 460 ft: hilly country.
Under the town center the state geologic map shows Baraga Group; Michigamme Formation, undivided (mixed-clastic, metagraywacke), from the Paleoproterozoic, 1.6 to 2.5 billion years old.
The section below crosses 2 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 21×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Mixed-clastic, metagraywacke. Age: Paleoproterozoic, 1.6 to 2.5 billion years old. About 17 mi of the line.
Sandstone. Age: Mesoproterozoic, 1 to 1.6 billion years old. About 7 mi of the line.

A raindrop that lands in Covington reaches Lake Superior by way of Kelsey Creek, the Sturgeon and the Portage: about 75 river miles. From there it moves on through the Great Lakes, over Niagara Falls and down the St. Lawrence to the Atlantic.
Lake on the way: Torch Lake.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Covington; river miles along the main stem, rounded.
